Question

please help me calculate these

According to a forestry database for a certain country, 5022 forest fires were started in a recent year, affecting 4,566,855 hectares of land. Of these, 2359 were caused by lightning, affecting 4,521,165 hectares of land; 2583 were caused by human activities, affecting 40,653 hectares of land; and the remainder were of unknown origin. Determine the relative frequency distribution of forest fire causes for the year. Describe the findings in a sentence or two. Find the relative frequency of forest fires started by lightning. The relative frequency of forest fires started by lightning is 47.0 %. (Round to one decimal place as needed.) Find the relative frequency of forest fires started by human activities. The relative frequency of forest fires started by human activities is 51.4%. (Round to one decimal place as needed.) Find the relative frequency of forest fires of unknown origin. The relative frequency of forest fires of unknown origin is 1.6 %. (Round to one decimal place as needed.) Describe these findings. Causes of forest fires are about equally split between lightning and human activities. Fires started by lightning are much common than the other two types of forest fires.
